"Late last year I learned that a claim had been made about me, going back to when I was 19. It was made on social media, when I was elected opposition leader.

"I will not go into details, except to say that the allegation was untrue and abhorrent. The allegation was made by someone I knew briefly at that time.

"There is absolutely no basis for the claim. The claim has now been thoroughly and vigorously investigated by police, as is entirely proper.

"I fully co-operated to clear my name. And that is what I have done. I freely answered all questions the police asked of me.

"Now the police investigation has concluded, I can make this statement.

"This has been deeply distressing for my family. I am thankful for the love and support of Chloe, and the support of my staff and parliamentary colleagues. Others who were aware of the investigation have acted with the utmost integrity by leaving the police to do their job.

"The police have now concluded the investigation. The decision speaks for itself. It is over. I have no intention of making any further comment."
